Integrating YANG Configuration and Management into an Abstraction and Control of TE Networks (ACTN) System for Optical Networks

Many network technologies are operated as Traffic Engineering (TE) networks. Optical networks are a particular case, and have complex technology-specific details. Abstraction and Control of TE Networks (ACTN) is a management architecture that abstracts TE network resources to provide a limited network view for customers to request and self-manage connectivity services. It also provides functional components to orchestrate and operate the network. Management of legacy optical networks is often provided via Fault, Configuration, Accounting, Performance, and Security (known as FCAPS) using mechanisms such as the Multi-Technology Operations System Interface (MTOSI) and the Common Object Request Broker Architecture (CORBA). FCAPS can form a critical part of configuration management and service assurance for network operations. However, the ACTN architecture as described in RFC 8453 does not include consideration of FCAPS. This document enhances the ACTN architecture as applied to optical networks by introducing support for detailed YANG Configuration and Management, effectively adding support for FCAPS. It considers which elements of existing IETF YANG work can be used to solve existing scenarios and emerging technologies, and what new work may be needed. In doing so, this document adds rich-detail network management (RDNM) to the ACTN architecture. This enhanced architecture may then be used to evolve networks from CORBA and MTOSI FCAPS interfaces to IETF-based YANG and RESTful APIs.
